MACHINE FOR FINISHING PLOW-HANDLES.

SPECIFICATION forming part of Letters Patent No.

325,258, dated September 1,1885.

Application filed June 11, 1884. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM G. MARGI DANT, of Hamilton, Butler county,Ohio, have invented certain new and useful Improvements in Machines forFinishing Plow Handles, of which the following is a specification.

This invention relates to a machine for finishing or sandpapering thesides and edges of plow-handles after they have been properly formed.

The invention will be fully understood from the following description,taken in connection with the accompanying drawings, in which-- Figure 1is a side View, and Fig. 2 an end view,at the unbent end, of aplow-handle; Fig. 3, a side elevation of my improved machine; Fig. 4c, aplan of the same with part of the upright framingin section; Fig. 5, anend view of the same with some of the framing broken away, the endviewed corresponding with the right-hand end of Fig. 3 and the upper endof Fig. 4; Fig. 6, an enlarged view of a plowhandle in section, therocking table upon which it is supported, and the bearing of the rockingtable.

In the drawings, A represents a plow-handle, B, the bent end portion ofthe same, 0, the convex edges of the handle, and D the flat sides of thehandle.

The sandpapering by machinery ofa handle of this kind presents seriousproblems by reason of the bent end portion,which prevents its being fedinto machinery of known construction, and by reason of its convex edges,which are not adapted to be sandpapered in machinery of knownconstruction.

My improved machine operates upon the side and edges of such handles,but is not intended for finishing the bent portion- Proceeding with thedescription: In Fig. 3,E represents thehorizontal frame-work of themachine, F, a vertical frame-work forming a portion of themachineframing at the initial end of the machine-that is, the end to theright of Fig. 3; G, apair of vertically-arrangedsandbelts carried by theframe-work F, and so disposed, as indicated in Fig. 5, that the twobelts shall run in close proximity, so as to operate upon the twoopposite faces of any article fed horizontally between them, theapproximate surfaces of the two belts having a downward direction ofmotion; H, a narrow table between the sand-belts, and arranged tosupport the work as it is fed between the belts; I, vertical feed-rollsfor carrying the work along upon the table H and between thesandbelts;J, an endless carrier for carrying the work forward after it leaves thetable H; K, horizontal feed-rolls near the left end of the machine, forcarrying the work forward from the endless carrier; L, asand-druinarranged horizontally to act upon the upper surface of an article movedforward by the feed-rolls K; M, a similar sand-drum arranged to act uponthe under surface of the article; N, a vibrating frame supporting theupper drum; 0, levers by which the sand-drums are reciprocatedlongitudinally as they revolve.

In the operation of this machine a plowhandle is started bent endforemost, and with the bend upward, into the right endof the machine onthe table H, between the first pair of vertical feedrolls, whichfeed-rolls, how ever, do not at present grasp it, being set too farapart. The bend of the handle is pushed through between the sand-beltsand between the second pair of vertical feed r-oils, and then the handleis turned upon its side, after which operation the vertical feed-rollstake hold of it and feed it properly through between the sand-belts,which act in an obvious manner upon the edges of the plow handle. lVhilethe handle is being thus fed the vertical feed rolls reciprocate up anddown. This gives to the plow handle a rotatory motion upon its axis, thetable H having a rocking motion in conformity to the rotatory motion ofthe handle. 13y this means, which will be more fully described, theconvex edges of the plowhandles become properly dressed by thesandbelts, and the handle is delivered upon the carrier J, whichdelivers it to the horizontal feed-rolls, which feed it between the twosand-drums, which finish the side surfaces of the handles, after whichthe handle leaves the machine. XVhile the sand-drums are acting upon thehandle they are reciprocated longitudinally by means of a cam acting onlevers 0, whereby sand-streaking of the finished surfaces is guardedagainst.

In the drawings, P represents a shaft in front of the first pair ofhorizontal feed-rolls;

the top pulleys of the sand-belts; R, a pivoted yoke for each top pulleyQ, in which the pulley isjournaled; S, a lever pivoted to the uprightframing upona pivot with a horizon tal axis, and having the yoke Rpivoted upon a vertical axis to its inner end; T, astrain- Weight fittedto adjust along the outer end of lever S, of which,with its accessories,there is one for each of the sand belts; U, .a longitudinal shaft at thesand-belt end of the machine,

lying between the acting faces of the two sandbelts and disposed somedistance below the table H; V, a crank-shaft disposed below the plane ofthe shaft U; W, aconnectingrod reaching upward from the crank upon theshaft V to an arm or lever secured to the longitudinal shaft U; X, adoubleended horizontal lever secured to the front end of shaft U; Y, adouble-ended horizontal lever secured to the table H; Z, linksconnecting the ends of lever X to the ends of lever Y; a, vibrating rodsvertically arranged and engaging circumferential grooves in the verticalfeed-rolls, which feed-rolls are free to reciprocate upon thespindles-which drive them; I), double-ended horizontal levers secured tothe shaft U and connected to the lower ends of the rods a,- c, a bearingsecured to the frame of the machine and supporting therear end of therocking table H; d, actuating bevel-- gearing at the foot of thespindles of the vertical feed-rolls, by which motion is imparted to themthrough crossshafts; e, which carry the spindles of the verticalfeedrolls upon each side of the table E; f, shanks projectinghorizontally from the housings a into supporting-sockets secured to theframing; 9, weighted bell-crank levers pivoted to the framing andarranged to press the housings 6 toward the table of the two sand-belts;z, castings secured to the frame at the sand drums, and provided withvertical sockets; j, setscrews worked upward into these sockets, and ishorizontal tables arranged between the sand-drums'and provided withshanks fitting the sockets.

By means of the yoke-and lever arrangement at the top of the frame thesand-belts are kept uniformly and automatically strained, and the yokesB, being pivoted, permit the top pulleys to maintain themselves inalignment with the base pulleys, the sand-belts being at all times atliberty to yield vertically, and

consequently laterally, to suit the width of the work upon which theyoperate. The shaft V, through its crank and connecting-rod,

the housings.

H; h, the base-pulleys serves to give a partial rotation to the shaft U,and thus oscillate the levers X and b, which are secured to it. Thelever X, through the medium of the linksZ and lever Y, rocks the table Hin such manner as to properly present the convex edges of theplow-handle to the action of the sand-belts; The levers b, through themedium of the rods a, serve to reciprocate vertically the verticalfeedrol1s, and thus impart the proper motion to the plow-handle as it isfed by the rolls, the feedrolls being splined to their spindles, so asto be revolved by them, but be at liberty to reciprocate upon them. Asthe plow-handle is fed between the'sanddrums, it rests upon the tables70, which can be adjusted vertically, so as to subject the under side ofthe plow-handle to the proper action of the lower'sanddrum. Thevibratable frame N, carrying the upper sand-drum, is freely pivoted, andthe upper sand-drum is thus at liberty to accommodateitself to the uppersurfaceofthe plowhandle.

It is probablysufficient to say to the skilled machine constructer thatprovision should be made for imparting the driving motions to thevariousparts; but it may not be out of place to indicate the means employed inthe arrangement of driving apparatus in the con struction shown in thedrawings. The motion may be transmitted by belting, or gearing, or chainbelting, and the general arrangement will be understood from a verybrief reference to the drawings. Pulley 1 receives'a belt from theline-shaft or any other suitable driving-shaft of the factory. Thispulley is fast to shaft 2, which carries pulleys 3, which are to bebelted to pulleys 4 on the two sanddrums. Belt on pulleys 5 and 6 drivesshaft P, to which is secured cam 7, which oscillates the levers forreciprocating the sand-drums. Shaft P transmits motion through gearsSand 9 to the first pair of horizontal feed-rolls, which rolls drive thecarrier J, and may transmit motion to the second pair of horizontalfeed-rolls by chain, belt, or gears. Shaft P carries clutchedsprocket-wheel 10, the purpose of the clutch being to enable the motiontransmitted from its sprocket-wheel to be stopped or started atpleasure. Chain belt on wheels 10 and 11 revolves shaft 16, which drivesthe rear pair of vertical feed-rolls, the cross-shaft which drives thefront pair of vertical feed-rolls being driven bya chain belt on wheels12 and 13. Chain belt on wheels 14 and l5 drives the shaft V. Pulleys 17are on the shafts of the base pulleys of the sand-belts, and are .toreceive motion from a proper counter-shaft. 7

While this machine has been invented for thespecial purpose of finishingplow-handles, and while I call it a plow-handle machine, I anticipateits utility in the treatment of other articles of similar sectionalform.
